instructions. Here are my results:

Nothing happens after this step! Perhaps we're playing with different  
versions of mplayer?

mplayer didn't freeze here, but this is probably because something  
different happened in step two for the two of us.

Oh, are you running mplayer in virtualbox? Can you reproduce this  
problem when running mplayer in xmonad directly? Is xmonad running on  
the guest or the host (or both)?
